Application filed February 10, 1925. Serial No. 8,278

Our invention relates to improvements in threaded connecting members.

The object or our invention is to pro-video threaded connecting memberconstructed and arranged to connect two wooden members'together so thatthe threaded securing means are wholly out of si -ht so that a perfectoint is made, having the appearance of one piece and the members aremore particularly designed for connecting-the two pieces of a toiletseat together.

Another object of our invention is to provide a threaded member of thischaracter which is applied by pressure on the two members to be securedtogether,and thus dispense with labor in screwing the members and alsoinsure of the members being drawn up evenly at the same time, so thatthe faces and edges of the members will beflush, and a tight jointformed. I

A further object of our invention is to pro vide a simple cheap andefiiective threaded member of this character in which there is a greatsaving in time and labor in securing two pieces of wood together. r p

i In the accompanying drawings:

I Figure 1 is a top plan view or the two sections or a toilet connectedby our improved threaded members. I

Figure is an enlarged plan view clone of the two sections of a toiletseat showing the first step of the application of the connecting member,and showing the connecting member of a slightly modifiedform,

, Figure 3 is a perspective view of o'ncend oi the screw threadedconnecting-member showing four threads thereon.

Fi ure 4: is an end view of Figure 3Q Re'i'erring now to the drawings, 1represents one section of the seat and 2 the other section, which areadapted to be connected by our improved threaded connecting members andwhile we have shown this in the form of a seat, it will be understoodthat the sameco'uld. be used for connecting any two pieces of woodtogether. The threaded connecting members 3 as shown, are composed of abody portion having the right hand threaded portions at I one end andthe left hand threaded portion 5 extending inwardly to point adjacenttheends of the threaded member having a blank space 6 intermediate theinner ends of thethreads. Thisblank portion 6 between the threads is ofa diameter slightly less than thebored openings 9 and in the sections,to allow the same to prevent any liability of splitting and at the sametime allow of a slight spring b otween the two threaded portions, if thetwo openings 9 and 10 are not perfectly drilled. The outer ends of thethreaded portions are pointed as indicated at 7 and 8 which is adaptedto allow the end portions of the member to pass into the drill openings9 and 10 in the edges, of the sections to beconnected, so thatthe memberwill start into theopenings in their proper position parallel the faceof the sections.

Both the right and left hand threaded portions 4 and 5 of the member areprovided with tour threads 11, 12, 13 and let which form a greaterholding surface for the connecting memben-and due to the series ofthreads the same is more readily forced into the openings with lesspressure, and also insures a positive rotation oi" the threaded members,as the two members to be connected are forced together.

The two members to be connected together, as

herebetore stated, are provided with openings 5) andlO bored into theedges 0]": the same, par: allel the faces, and saidopenings being of adian'ieter slightly less than the threaded portion of the member, andthe connecting members are placed between the two sections to be securedtogether with their pointed ends 7 and 8 entering the openings 9 and 10,and pressure is applied to the two sections at the point A-B and themembers will rotate and travel inwardly into the bored openings, andsecurely draw the two sections together and hold them to formpracticallya solid unit.

In the modification shown in Figure 2 of the drawings, the threadedportions 4 and 5 extend into the center point and thus give alongerthread anda greater holding surface where the connecting member isused on narrow sections or members.

Having thus fully described our invention of such a pitch that theconnecting member is -What We claim is caused to rotateand cut its ownthreads by A threaded connecting member comprising pressure only in themembers to be connected. 0 I a central smooth portion, right and lefthand In testimony whereof We aifix our signa- 5 coarse Wood threadedportions on opposite tures.
